3a ICQ/5885s.- 26 27 A TTURNEI/ BERNARD F. KOCH, 0F CHICAGO, ILLINOIS.

v HORN.'

To all whom t may concern Be it known that I, BERNARD F. KOCH, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Horns, of which the following is a description.

My invention belongs to that general class of devices known as horns, and relates more particularly to that type of horn provided with a diaphragm therein and with a manu-Y allyv operable mechanism -for vibrating the diaphragm. Y

The invention has among'its objects the production of an improved horn'of the kind described, and particularly an improved mechanism for operating or vibrating the diaphragm. Y

rI`he device has among its further objects the production of a device of the kind described that is simple, compact, durable, efficient, and satisfactory, and that may be used'wherever found applicable.

To this end my'invention consists rin the novel construction, arrangement and combination'of parts herein shown and described, and more particularly pointed out in the claim.

In the drawings, wherein like reference characters indicate -like or corresponding parts, Figure 1 is a sectional view of my improved form of device, taken substantially on line 1, 1 of Fig. 2; Fig. 2 is substantially a sectional view taken on line 22 of Fig. 1; Fig. 3 is a sectional view taken substantially on line 3, 3 of Fig. 2, and Fig. 4 is a side elevation of the wheel 10 and portion of the associated parts.

Referring to the drawings, in which my -preferred form of device is shown, 1 and 2 represent shells of suitable material and form, forming the casing or body of the horn, the same being secured together and to a'transverse partition 3, having a suitably formed opening therethrough. Arranged proximate the partition 3 and secured to the same, is a diaphragm 4, which is preferably provided with an adjustable pin 5, which extends through the opening in the partition 3. The pin shown may be secured in position in any desired manner. As shown, it extends through a threided member 6, suitably secured on the diaphragm 4, and is locked in position by a lock nut 6. The partition 3 carries brackets 8 and 9, which are preferably formed as most clearlyshown in Speciiication of Letters Patent.

Application filed February 25, 1914. Serial No. 820,796..

Fig. 2 by cutting the partition and bending up a portion of the same.: The two standards carry a pin or shaft 11, upon which is rotatably'mounted a wheel 10, preferably of some weight. As shown, the wheel 10 is suitably mounted upon bushing 12, rotatably mountedupon 'the shaft 11, and which -is provided with a pinion 17, as shown. The wheel 10 is provided with a groove 15, about its'periphery, and pins 16. preferably of hardened material, arranged about the wheel and extending through the groove 15. As most' clearly shown in Figs.2 and 4, the wheel 10 is provided with an extended casing 20, which slidably carries a small pawl 18 `arranged to mesh with and engage in the teeth 17, a spring 21 normally maintaining the pawl in the position shown in Fig. 4. Any equivalent construction, however, may be substituted to operatively connect the wheel and pinion 17 when the pinion is rotated in the direction indicated by the arrow, which drives the wheel 10 in the same direction through the pawl 18. The resilient pawl, however, allows the wheel to spin, or the pinion 17 to be turned in the opposite direction, without turning the wheel in that direction.

The pinion 17 is driven by means of a gear segment or sector 25. As most clearly shown in Fig. 2, the segment is extended as at 24, and formed with an arm 22, which extends over the bracket 9 and is pivotally secured on the exterior of the bracket or standard 9 by a pin 23, or its equivalent. Suitably carried byv the partition is an operating arm or lever 26, the same being pivotally secured at 27 to a bracket 28, secured to the partition 3, or formed therefrom by cutting or bending up a portion'of the partition similar to the standards 8 and 9. The lever or farm 26 is connectedby a link 29 to the arm 22, the same being pivotally secured to the parts at 3') and 31 respectively.

The arm 26 is retrieved and normally resiliently maintained in the position shown in Fig. 3 bv a spring 33, which is secured to the partition 3, as Shown, the same being engaged by a lug or extension 34, and engages with the lug 35 on the lever 26. The arm or lever 26 is extended as at 32 to the exterior of the casing part 2, so that the same mav be manipulated as desired.

Then the thumb piece 32. or end of the arm 26, is moved to the dotted position shown in Fig. 3, through the link 29 andv 16. As the wheel 10 is driven, the pins 16" engage with the end of the pin 5 carried by the diaphragm, causing the same to be pushed into the position shown in (Fig. 1. As each pin passes, the resiliency of the diaphragm tends tov return yit to normal .posi. tion, and it .springs back, the pinpassing between two .pins 16. As the .wheel is driven at some speed, the diaphragm 4 is moved back and forth past its normal position when at rest, causing-a loud noise. The wheel 10 being of some weight, theftendency is fo-r the wheel to spin to a 4certain extent. If the pressure on the lever 26 'is reduced, or that is, the end 32 released, the arm is moved back to the initialposition indicated in Fig. 3. If it is again moved to the dotted position, the sound is repeated, and if moved immediately,- or back and forth, the sound maybe substantially continuous. e

Owing to the co-mpactness and simplicity of lthe device, it is particularly adapted for bicycles, motorcycles and cycle cars and automobiles, but it may, of course, be used wherever found applicable. -By the employment of the mechanism `herein described, one movement of the lever is suflicient to give considerable rotation to the wheel 10, so that the vibration extends over a number of times, making the sound more or less continuous rather than intermittent.

As most clearly sho-wn in Fig. 1, the partition 8 is preferably extended asi at 36, thence as at 35 to form a half of a bracket for securing the horn in place. A coperating clampingfmember 37 is secured thereto by bolts 38 (onlyfone being sho-wn) Any equivalent construction may, of course,l

be emploved.-v A very convenient :way-.of securmgtheparts ofthe casing together is show-n in Athls figure (Fig. 1.) infwhichthe shell vpart-1 is flanged asat v42,and thencev as at .41, so as to overlielth-e edgepf ,the plate or` partition 3. V.The other-part 2 of the casing is flanged as at 4Q, thence crimped or formed to overlie as at 39, so that the Copies ofthis patent may be obtainedior kfive cents each, by addressing the "Commissioner of Patents,

parts of the casing are secured together' and to the plate 34, without rivets, screws, or other connections. This makes the device easv and economical to manufacture. Any equivalent construction, however, may be employed. I have also shown the diaphragm 4 rcorrugated at 44, the purpose of the same being to -stiffen the diaphragm to some extent. This, however, is not essential.

Having thus described my invention,J it is obvious that various immaterial modifications may be made in the samewithout vdeparting from the spirit of my invention; hence Il do not wish to be understood as limiting myself to the exact form, construction, arrangement, or combination of parts herein shown and described, or uses mentioned.

llVhat I claim as new and desire to secure by Letters Patent is ln a horn of the kind described and in combination, a suitable two-part casing, provided with ay v transverse partition at their juncture, `having an opening therethrough, a sheetmetal diaphragm arranged proximate said partition with a space there* between and provided with a part extending therethrough at said opening, said partition formed with a standard on the side opposite said diaphragm, a shaft carried by said standard, a pinion rotatably arranged on said shaft, a toothed wheel rotatably arranged on saidv shaft, and arranged to cooperatewith the part on said diaphragm, means for actuating said pinion, comprising a. segment in mesh with said pinion and eX'- tending around the standard and pivotally securedy to the other side thereof, an actuating lever vpivotally carried by said partition, a link pivotally connecting saidv segment extension with Said lever, and means for resiliently maintaining said parts in initial position. I p f Intestimony whereof, I. have hereunto signed my name in the presence of two subscribing witnesses.
